Here is a reprex:

save as main.asm:
section .text
        mov rdi, 1
        lea rbx, [rel values + rdi * 8]

        mov rdi, 1
        lea rbx, [values + rdi * 8]

section .data
        values dq 1, 2


Then run:

nasm -Wall -f elf64 main.asm
objdump -S -M intel main.o

You will see that rel_bug and non_rel are identical instructions
